Missing Growing Pains actor Andrew Koenig has a great relationship with his famous father from Star Trek, but didn’t want to be called “Mr. Chekov’s son,” Lance Miccio told RadarOnline.com exclusively.

Micci, who worked with Andrew for six years collaborating on TV and films, says that as an adult, Andrew is trying to make a name for himself. “He was very proud of being Walter Koenig’s son,” Micco said. “He just didn’t want to be introduced as Mr. Chekov’s son. He didn’t like that.”

But he clarified, “I know his parents are very concerned. I know that he had a good relationship with his dad and his mom. That’s not the issue.”

And he also wanted to get past being the child actor from Growing Pains “because as an actor he’s grown a lot as a man in the way he approaches things. He didn’t want to be stereotyped or pigeonholed into that one character. If you know Andrew, he’s very multi layered talented.”

Andrew has been missing since Valentine’s Day and the last cell phone correspondence from him was on February 16th. But, Lance says, Andrew doesn’t like using a cell phone.

Lance is also revealing more details about Andrew’s lifestyle. Besides being introspective and a vegan, he also had a lot of friends, “I know he had a very busy social life because I had to plan my work around it.”
